“and Pixie will be your image wrangler…”

Behind the Scenes of an Exhibit

Of all the types of writing projects I’ve done, working on exhibits has got to be the most involved and complex. For one thing, I don’t do it by myself. Oh sure, I do the writing and usually a lot of the research into the topic. But, there are always others involved in what is a team effort.

Take the one I just finished for the California Academy of Sciences. The  name of the exhibit is Altered State and is about climate change in California.  I estimate that I wrote about 10,000 words for the exhibit, all to explain how climate change works and how it is affecting various ecosystems up and down the state. It’s a complex topic

Like I said, I didn’t do this in a vacuum. I had a wonderful support crew including a director/producer, a researcher, a scheduler, a mom-confidant and, straight from the movie-making world, I had wranglers. Where did these people come from?

They work for Cinnabar, the company I worked under the direction of, comprising a group of people who are involved in just about every aspect of background production for films and exhibits you can imagine. They work on movies, theme parks, museums, and in-store exhibitry. Cinnabar, and its CEO Jonathan Katz, basically put together a really good support crew so I could focus on the subject and write exhibit copy in record time (four months start to finish). They also contracted and worked with designers such as VolumeSF, to design the exhibits. I really don’t know how many people ultimately worked on the exhibits (and they also put together a fine set of exhibits about Madagascar and the Galapagos Islands using another writer. But after seeing the exhibits in person last month and meeting the Academy’s in-house writers and experts, I came away really impressed with everybody who worked on these exhibits.

Well, what about those wranglers, you ask?  These are people who collect items needed for the production of exhibits (and film sets, etc.). In my case, we needed to “wrangle” images and quotations (quotes from poetry, articles, etc.).  A fine lady named Pixie Cearbhaill was my image wrangler and through all the long days and nights when I’d be writing and need to see an image, Pixie would find it and send it to me or send links to possible images she was working on acquiring for use.

In addition, although I could (and did) do research myself, I also had a research “wrangler” Natasha Fraley, who could come up with papers and references for me almost on demand and often served as “quote wrangler.” I also had a great deal of support from Sophia Katz (of Cinnabar), and Carol Tang, Aaron Pope, and others at the Academy itself.  Cinnabar’s Jeannie Lomma was my sanity-check person, the producer’s producer who kept us all from going completely batty. And, there were many others who helped keep me on track and more or less on time throughout the vagaries of editing, design changes, and other processes that keep an exhibit project hopping.

As with the Griffith project I worked on in 2005 and 2006 (and for whom I still do work from time to time), I remain amazed at the complexity and teamwork it takes to put a major science exhibit together. It begins with an idea and wraps up as the proud work of many dedicated professionals.  We couldn’t do it without each other’s smarts.

Orbiting Piles of Rubble

Where Do They Come From?

Not everything in the solar system is as solid as it looks at first glance. Take Phobos, the larger moon that orbits Mars. It looks solid, but it may well be an orbiting pile of rubble. Now where would that rubble come from?  Most likely a collision of some kind.

The European Space Agency’s Mars Express mission passed by Phobos this past summer and took a series of high-definition stereo images and data. That information got fed into a 3D modeling program that is letting astronomers measure this moon’s characteristics, including its volume and the interacting gravitational tugs between Mars and Phobos.

The analysis suggests that Phobos may be more of an asteroid than a body that evolved as a single piece.

The closest match that scientists can make for Phobos is with D-class asteroids, which are highly fractured and riddled with caverns. They are really more like pieces of rock that stick together by gravity. Scientists refer to these loosely grouped rock piles as “rubble piles.”

So, if it’s likely that Phobos didn’t form around Mars, how did this orbiting rocky junkyard get into its current equatorial orbit around Mars?  There are two ideas. First, Mars gravitationally “captured” a passing rubble pile, which settled into orbit as Phobos. Deimos, the other moon, was likely captured the same way.

Phobos: an orbiting rubble collection?

The other possibility is that a meteorite (a chunk of rock from an asteroid) smashed into early Mars and pieces of it got blasted back into space. Eventually, they clumped together into a rubble pile of rocks bound together by gravity, forming what we know today as Phobos.

In the near future the Russian space agency will send a probe called Grunt to Phobos to do study this moon and collect samples of rock for further study.  Studies of rocks and continuing studies of Phobos’s subsurface structure (done using radars onboard the Mars Express spacecraft) will help astronomers figure out at least some of Phobos’s past and possibly even its origin.

As they say: stay tuned!
